- Seed germination using watercress and runner bean seeds
- The upside down water experiment
The pupils were given the task of creating the ideal conditions for watercress and runner bean seeds to germinate using only cotton wool, paper towels, water and heat. Once they had their seeds placed in the containers, the pupils made sure that they were kept watered and warm to help the seeds to germinate. "Green fingers" aplenty as you'll see from the photos below!
For the upside down water experiment, the pupils had to use a glass of water and a piece of card to show atmospheric pressure at work. The force from the atmospheric pressure holds the card up and the low pressure zone in the glass prevents the water’s weight from pushing the card down. The pupils were so confident (despite the somewhat nervous facial expressions in the photos) that the water would remain in the glass when turned upside down, they were even willing to put the glass of water over their head. We're delighted to report that there were no major spillages and there were no wet heads as a result either!
